Error when try to delete files that existed

[Sam]

Hello,

I used RadAsyncUpload control to accept a upload zip file. My zip file contains text delimiter files.  I am able to unzip it to a temporary directory, but if I try again with the same zip file I get error something like "...because it is being used by another process." (at line 17)

Below is my method to unzip:

01.private static void UnpackAndSaveFile(ZipPackageEntry entry, string destinationPath)
02.    {
03.        Stream stream = entry.OpenInputStream();
04.        var fileName = destinationPath + "\\" + entry.FileNameInZip;
05.
06.        var directoryName = Path.GetDirectoryName(fileName);
07.
08.        if (directoryName != null)
09.        {
10.            if (!Directory.Exists(directoryName))
11.            {
12.                Directory.CreateDirectory(directoryName);
13.            }
14.
15.            if (System.IO.File.Exists(fileName))
16.            {
17.                System.IO.File.Delete(fileName);
18.            }
19.
20.            StreamReader reader = new StreamReader(stream);
21.            string text = reader.ReadToEnd();
22.            File.WriteAllText(fileName, text);
23.        }
24.    }

Please help,

Thanks,
Sam

Hello Sam,

After examining the code I noticed that the StreamReader is not closed which is probably causing the described behavior. Please call reader.Close() before File.WriteAllText or include a using statement(as demonstrated here) and test whether this resolves the problem.
